1.199 ! dholland 1: $NetBSD: UPDATING,v 1.198 2009/07/09 07:31:54 mrg Exp $
1.1 abs 2:
1.123 jmc 3: This file (UPDATING) is intended to be a brief reference to recent
4: changes that might cause problems in the build process, and a guide for
5: what to do if something doesn't work.
1.1 abs 6:
1.123 jmc 7: For a more detailed description of the recommended way to build NetBSD
8: using build.sh, see the BUILDING file.
9:
10: Note that much of the advice in this UPDATING file was written before
11: build.sh existed. Nevertheless, the advice here may be useful for
12: working around specific problems with build.sh.

16: Recent changes:
17: ^^^^^^^^^^^^^^^
1.138 lukem 18:
1.198 mrg 19: 20090709:
20: Native Xorg was upgraded again. Builds will probably fail again
21: without a clean objdir, at least for src/external/mit/xorg.
22:
1.197 mrg 23: 20090616:
24: Native Xorg was upgraded. Builds will need a clean objdir for
25: src/external/mit/xorg. Upgrading a system from sets will not
26: work properly yet as the /usr/X11R7/lib/X11/xkb/symbols/pc
27: subdirectory has been changed into a file, and this needs to
28: be manually "rm -r"'ed before installing xbase.tgz.
29:
1.195 perry 30: 20090501:
31: Several new functions were added to string.h/libc, and this
32: can cause autoconf problems during the tool build for people
33: who fail to clean out their tools objects properly. If you
34: note messages about stpcpy, stpncpy or strnlen accompanying a
35: failure during the tool build, clean out all your tools
36: objects and start again.
37:
1.194 mrg 38: 20090325:
39: The i386 port was switched to i486 default toolchain. This requires
40: cleaning your src/tools directory and $TOOLDIR and rebuilding them.
41:
1.192 skrll 42: 20090126:
1.193 skrll 43: The __posix_fadvise50 system call changed assembly stub type. You need to
44: 'rm -f __posix_fadvise50.*' in the libc build directory to avoid using
1.192 skrll 45: the old assembly stub.
46:
1.191 joerg 47: 20090202:
48: pkg_install now depends on the pkgdb cache for automatic conflict
49: detection. It is recommented to rebuild the cache with
50: ``pkg_admin rebuild''.
51:
1.184 christos 52: 20090110:
53: time_t and dev_t have been bumped to 64 bit quantities. To upgrade:
54: 1. Make sure your kernel has COMPAT_50 in it. Build and install.
1.188 christos 55: This is needed even in the MODULAR kernel because there is
56: conditionally compiled code in rtsock.c.
1.184 christos 57: 2. make sure build.sh completes and the binaries in a chroot work
58: before installing.
59: 3. If you don't use build.sh and you build directly to root, and
1.187 dholland 60: your build breaks in the middle, don't despair. Make sure headers
1.184 christos 61: are installed properly, and start building libraries first libc
62: and libutil, install them and then continue building all the
63: libraries in src/lib and src/gnu/lib and install them. Once
64: the new libraries are installed, you can restart the build.
65: 4. If you compile packages and you notice link time warnings,
1.189 hubertf 66: rebuild the required packages to update their shared libraries.
67: Any package you rebuild will require rebuilding all the packages
68: that depend on it.
1.186 christos 69: 5. Next time you run pwd_mkdb with the new binary, the file
70: will be upgraded and it will not be backwards compatible.
1.190 apb 71: 6. The utmpx/wtmpx files (/var/run/utmpx and /var/log/wtmpx, see
72: lastlogx(5)) have been versioned, and there is a heuristic
73: for utmp. You are better off removing the old files after
74: upgrading. The automated clearing of /var/run during
75: boot, and the automated rotating of files in /var/log by
76: newsyslog(8), may mean that you do not have to remove the
77: files manually.
78: 7. The optional accounting file (/var/account/acct, see
79: accton(8)) has not been versioned, and will need to be
80: removed. The automatic rotation of the accounting file by
81: /etc/daily limits the bad consequences of failure to remove
82: the file.
1.196 dholland 83: 8. Application software that writes time_t to binary files on
84: disk will break or need attention. Most notably: if you are
85: using PostgreSQL < 8.4, you need to dump your databases,
86: rebuild PostgreSQL with the new time_t, then restore.
1.185 jmcneill 87:
1.183 pgoyette 88: 20081219:
89: config(1) has been updated, and one of the files it creates -
90: swapnetbsd.o - has changed format. You need to rebuild config
91: (done automatically by build.sh) and then you need to rerun
92: config on all kernel configuration files before rebuilding those
93: kernels.
94:
1.181 cube 95: 20081205:
96: If you build with MKX11=no, you should remove /etc/rc.d/xdm and
97: /etc/rc.d/xfs from DESTDIR because those files were moved to the xetc
98: set and will appear as extra files for MKX11=no update builds.
1.178 lukem 99:
1.179 tsutsui 100: 20081122:
1.182 tsutsui 101: On i386, various kernel options(4) in GENERIC including
1.180 wiz 102: file systems have been disabled and moved into kernel modules.
103: Before trying a new GENERIC kernel, you have to prepare the
1.179 tsutsui 104: following files as well as a new GENERIC kernel:
105:
106: - build and install kernel modules from src/sys/modules
107:
108: - install the latest bootloader, which will load a module
1.180 wiz 109: for the file system from which the kernel is loaded automatically
1.179 tsutsui 110:
1.180 wiz 111: If you have to load your kernel from a file system which is not of
112: the same type as the root file system, you have to load the necessary
113: file system module manually on the boot prompt or in the boot.cfg file.
1.179 tsutsui 114:
1.178 lukem 115: 20080827:
116: If you built and installed a libc from sources between
117: 2008/08/20 and 2008/08/26 you got a broken strtouq(3)
118: which results in false errors reported by lint(1).
119: Since this breaks the libc build itself, manual help is
1.180 wiz 120: needed -- lint must be disabled temporarily, e.g.:
1.178 lukem 121: $ (cd lib/libc && make MKLINT=no dependall install)
122:
1.177 christos 123: 20080813:
124: MKDEBUG build was broken because the .depend files did not know
125: about .go files. You need to remove all .depend files and rebuild.
126:
1.175 simonb 127: 20080731:
128: WAPBL (metadata journaling support) has been added, but at this
129: time isn't backwards compatible with pre-WAPBL aware kernels
130: and userland (fsck_ffs in particular). Please make sure you
131: don't use a journaled filesystem with an older kernel/userland,
1.176 simonb 132: especially an uncleanly mounted journaled filesystem. WAPBL
133: also requires the super block to be in the UFS2 format. You
134: can use fsck_ffs -c 4 to update the superblock format.
1.175 simonb 135:
1.174 lukem 136: 20080721:
137: Assembler warnings are now fatal if $WARNS>0 and $NOGCCERROR
138: isn't defined.
139:
1.173 freza 140: 20080531:
141: The ioctl number of DRVSUSPENDDEV command on /dev/drvctl changed
142: from 125 (conflicted with DRVCTLCOMMAND) to 129. The drvctl(8)
143: utility needs to be rebuilt and reinstalled as older binaries
144: won't work correctly. The following sequence of commands:
145:
146: $ (cd sys/sys/ && nbmake-$arch includes)
147: $ (cd sbin/drvctl/ && nbmake-$arch clean)
148: $ (cd sbin/drvctl/ && nbmake-$arch all)
149:
150: leaves new drvctl utility in sbin/drvctl build directory.
151:
1.172 lukem 152: 20080503:
153: The <bsd.lib.mk> variable MKPRIVATELIB was renamed to LIBISPRIVATE.
154:
1.171 he 155: 20080521:
156: For a while, unprivileged UPDATE builds would fail to
157: succeed at the checkflist stage, complaining that
158: ${DESTDIR}/stand/<arch>/ did not exist. A fix for this
159: problem was committed to share/mk/bsd.kmodule.mk, revision 1.9.
160: If you already hit this problem, update the .mk file,
161: remove ${DESTDIR}/stand/<arch>, and re-run the build.
162:
1.174 lukem 163: 20080303:
164: Linker warnings are now fatal if $WARNS>0.
165:
1.170 christos 166: 20080126:
167: The posix_fadvise system call has been changed from an assembly
168: stub, to a c file that calls an assembly stub. You need to
169: 'rm -f posix_fadvise.* .depend' in the libc build directory to
170: avoid using the old assembly stub.
171:
1.168 joerg 172: 20071209:
173: The acpiec(4) driver has been split into two attachments. If you
174: get ACPI errors before the attachment, please update your kernel
1.169 wiz 175: configuration file appropriately or see GENERIC for more details.
1.168 joerg 176:
1.166 xtraeme 177: 20071115:
178: The it(4) driver has been renamed to itesio(4) and the old port
179: argument specified in the kernel configuration file is not valid
180: anymore. The itesio(4) driver now uses the Super I/O address port
181: rather than the EC address port. Please update your kernel
1.167 wiz 182: configuration file appropriately or see GENERIC for more details.
1.166 xtraeme 183:
1.165 jmmv 184: 20071028:
185: The pccons(4) driver has been removed from the NetBSD/shark port.
186: You need to update any custom kernel configuration file you have
187: to remove any references to pccons (which includes removing the
188: now useless XSERVER option) and replace them with the correct
189: entries for the wscons driver. See the GENERIC configuration file
190: for more details.
191:
1.164 gdt 192: 20070913:
193: A latent bug in dhclient/dhcpd that caused it to be unable to
194: enumerate interfaces was fixed. The bug began to cause
195: problems after 20070911 when the kernel's SIOCGIFCONF
196: implementation was repaired. From 20070529 to 20070911 racoon
197: could not enumerate interfaces. (These are noted because
198: normal kernel/userspace version matching hygiene is not
199: sufficient to avoid this problem.) Ensure that both kernel
200: and userland are from after 20070913.
201:
1.163 joerg 202: 20070703:
1.199 ! dholland 203: nbinstall has been renamed ${MACHINE_GNU_ARCH}-install. It
! 204: calls the target-specific strip program, and the logic to pass
! 205: down STRIP from make has been removed. This requires a
! 206: re-installation of tools.
1.163 joerg 207:
1.161 dsl 208: 20070422:
209: The way OS emulations lookup filenames inside the emulation root
210: has been changed. Rather than modify the pathname (and copy back
211: to userspace) namei() and lookup() directly check the emulation
212: root. One side effect is that absolute symlinks inside the emulated
1.167 wiz 213: root file system will be relative to that file system - unless they
1.161 dsl 214: start /../ this is useful when the emulated root is a real install
215: that has such links.
216: This might affect symlinks that have been added to reference outside
217: the emulated root.
218:
1.160 jmcneill 219: 20070412:
220: The pckbc driver on sgimips IP32 has been removed. Use macekbc
221: instead. See the GENERIC32_IP3x kernel configuration for an
222: example.
223:
1.159 gdt 224: 20070319:
225: src/lib/libc/Makefile revision 1.129 broke libc and ld.elf_so
226: on many platforms due to incorrect flags settings. If you
227: updated and built after about 20070315, do "nbmake-$arch
228: cleandir" in src/lib/libc and src/libexec/ld.elf_so to force a
229: rebuild of object files that might have been built
230: incorrectly, and ensure that you have at least
231: src/lib/libc/Makefile 1.130.
232:
1.158 dbj 233: 20070210:
234: src/sys/sys/{sa.h,savar.h} were removed.
235: find ${OBJDIR} \( -name .depend -o -name '*.d' \) -print \
236: | xargs egrep -l '/sa.h|/savar.h' | xargs rm
237: will allow dependencies on those files to get get rebuilt
238:
1.157 apb 239: 20070209:
240: The threading model was changed when the newlock2 branch
241: was merged to NetBSD-current. If you boot with a new
242: kernel (version 4.99.10), then you also need a new pthread
243: library (/usr/lib/libpthread.so.0.7). If you boot with
244: an old kernel, then you need the old pthread library
245: (/usr/lib/libpthread.so.0.6). Provided you keep the kernel and
246: the pthread library in sync, old threaded applications should
247: continue to work with an old or new kernel. Note that named(8)
248: is the only threaded application in the base system.
249:
1.154 he 250: 20061214:
251: Following the move of string_to_flags() and flags_to_string()
252: from the bin/ls/ sources to libutil, users doing UPDATE builds
253: will need to do a "make cleandir" in
254: tools/mtree/, tools/makefs/, tools/binstall/, tools/pax/,
255: bin/pax/, bin/ls/, usr.sbin/mtree/, usr.sbin/makefs/,
1.156 he 256: usr.bin/xinstall/, libexec/ftpd/, rescue/, as well
257: as the installation images in distrib/
1.154 he 258: in order to excise stale references to the old stat_flags.h header
259: file in the ls sources -- stat_flags.h has been removed.
260:
1.152 christos 261: 20061108:
262: The configure script used in the src/tools/gcc compiler has been
263: changed to indicate that our libc has ssp support built-in and
264: does not depend on -lssp and -lssp-nonshared. You'll need to
265: make clean in src/tools/gcc first to rebuild the compiler.
266:
1.151 rpaulo 267: 20061009:
268: The sysctl variables net.inet{,6}.tcp{,6}.newreno are no longer
269: available. Use net.inet{,6}.tcp{,6}.congctl.selected instead.
270:
1.150 bjh21 271: 20060814:
272: The vt, vidcconsole, kbd, and rpckbd drivers on acorn32 have been
273: withdrawn. Use vidcvideo and pckbd instead. See the GENERIC
274: kernel configuration for an example. X servers from the last
275: few years should cope.
276:
1.149 christos 277: 20060703:
278: MPACPI is no more. We always configure PCI interrupts using ACPI
279: if we have an ACPI kernel. The option MPACPI_SCANPCI has been renamed
280: to ACPI_SCANPCI. Thanks to work from fvdl.
281:
1.148 dogcow 282: 20060627:
283: socket(2) has changed, and its system call has been versioned.
284: For userlands with the old version of socket(2), make sure that
285: your kernel has 'options COMPAT_30' set, or else 'bad system call'
286: errors will result.
287:
1.1 abs 288: Hints for a more successful build:
289: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
1.123 jmc 290: Use build.sh, but do not use its "expert mode":
1.132 jmmv 291: This will automatically build the tools in the
1.123 jmc 292: correct order, and it will keep the tools and the
293: new build products from interfering with the running
294: system. This will allow you to ignore most of the
295: other advice in this file.
1.2 mrg 296: Build a new kernel first:
297: This makes sure that any new system calls or features
298: expected by the new userland will be present. This
299: helps to avoid critical errors when upgrading.
1.1 abs 300: Use object directories:
301: This helps to keep stale object
302: files from polluting the build if a Makefile "forgets"
303: about one. It also makes it easier to clean up after
304: a build. It's also necessary if you want to use the
305: same source tree for multiple machines.
1.123 jmc 306: To use object directories with build.sh:
307: a) invoke build.sh with the "-M" or "-O" options.
308: To use object directories without using build.sh:
1.1 abs 309: a) cd /usr/src ; make cleandir
1.2 mrg 310: b) Add "OBJMACHINE=yes" to /etc/mk.conf
311: c) Add "MKOBJDIRS=yes" to /etc/mk.conf
1.1 abs 312: d) cd /usr/src ; make build
1.2 mrg 313: Note that running "make obj" in a directory will create
314: in obj.$MACHINE directory.
1.1 abs 315: Build to a DESTDIR:
1.123 jmc 316: This helps to keep old installed files (especially libraries)
317: from interfering with the new build.
318: To build to a DESTDIR with build.sh, use the "-D" option.
319: To build to a DESTDIR without using build.sh, set the DESTDIR
320: environment variable before running make build. It should be
321: set to the pathname of an initially empty directory.
322: Problems: if you do not use build.sh, you might need to
323: update critical utilities without using DESTDIR since
324: nothing is executed from what is installed in DESTDIR.
325: (See critical utils, below.)
1.1 abs 326: Build often:
327: This keeps critical utilities current enough to not choke
328: on any other part of the source tree that depends on up to
1.123 jmc 329: date functionality. If you use build.sh, you should not have
330: this problem.
1.1 abs 331:
332: What to do if things don't work:
333: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
334: When things don't work there is usually a few things that commonly
335: should be done.
336: 1) make includes
337: This should be done automatically by make build.
338: 2) cd share/mk && make install
339: Again, automatically done by make build.
340:
341: Failsafe rebuild of a small part of the tree:
342: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
343: To make sure you rebuild something correctly you want to do
344: something like the following:
345: 1) Make sure the includes and .mk files are up to date.
346: 2) Make sure any program used to build the particular
347: utility is up to date. (yacc, lex, etc...)
348: 3) cd ...path/to/util...
349: make cleandir
350: rm ...all obj directories...
351: make cleandir # yes, again
352: make obj
353: make depend && make
354:
355: Failsafe rebuild of the entire tree:
356: ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
357: If you really want to make sure the source tree is clean and
1.2 mrg 358: ready for a build try the following. Note that sourcing /etc/mk.conf
359: (a make(1) Makefile) in this manner is not right, and will not work
360: for anyone who uses any make(1) features in /etc/mk.conf.
